An adhesive is provided which comprises: (a) 100 parts by weigth of a linear hydrogenated tri-block copolymer of a vinyl aromatic hydrocarbon and a conjugated diene which has a coupling efficiency of 45 % or greater and which has a peak molecular weight of from 50,000 to 150,000; (b) from 30 to 110 phr of an endblock resin, a low molecular weight vinyl aromatic hydrocarbon, preferably alpha methyl styrene or styrene; and (c) from 80 to 210 phr of a hydrogenated hydrocarbon resin having a softening point below 35 C, wherein the following relationships are satisfied: H - 1.6E < 93, H + 1.3E > 175, H + 6.8E < 854, where H is the amount of hydrocarbon resin in phr and E is the amount of endblock resin in phr. |
